That little countdown on Britney Spears‘ official website that you’ve been wondering about? Here’s one clue about what to expect: Britney fansite BreatheHeavy reports that an email went out to employees at various Las Vegas area hotels inviting them to “come play a part in the biggest announcement in Las Vegas Entertainment History” on September 17, the same date to which Spears’ calendar is currently counting down.

The note continued: “Expect this event to generate global media attention, so you don’t want to miss out!” Ahem.

As if the expectation that whatever Britney’s announcing is significant enough to “generate global media attention” isn’t enough to secure her status as a living legend (you can look but don’t touch), producer Sean Garrett has spilled some more (rather vague) information about the upcoming duet between Spears and Miley Cyrus for Cyrus’ upcoming masterpiece BANGERZ. When the interviewer described the collab as potentially “epic,” Garrett had this to say:

“That’s the only way we know how to do it. I love both of them. That right there is iconic. You see now, I’m living life.”
